Support flexible configuration of run_prometheus.sh

Feature Request

Is your feature request related to a problem? Please describe:

1、Limit prometheus query spreading:
--query.timeout="5s" # default 2m
--query.max-concurrency=5 # default 20

2、Speed up restart time:
--enable-feature=memory-snapshot-on-shutdown

3、Enable WAL compression:
--storage.tsdb.wal-compression

All these optimizations need to be configured through run_prometheus.sh，eg：
exec bin/prometheus/prometheus
--config.file="/data1/webank_test11/tidb-deploy/prometheus-9291/conf/prometheus.yml"
--web.listen-address=":9291"
--web.external-url="http://172.16.4.204:9291/"
--web.enable-admin-api
--log.level="info"
*--query.timeout="500ms"
--query.max-concurrency=1
--enable-feature=memory-snapshot-on-shutdown *
--storage.tsdb.path="/data1/webank_test11/tidb-data/prometheus-9291"
--storage.tsdb.retention="30d"

Teachability, Documentation, Adoption, Migration Strategy:

Start by locating run_prometheus.sh and review how it assembles the Prometheus command. Make the requested query, restart, and WAL-compression options configurable through that script, while preserving existing behavior when they are not set. Done means the script can pass these options to Prometheus as described in the issue.
